' to prevent smut,-and whereinithere is provided a conveyor for conveying the ain through a cleansing solution, to thoroiighly clean the grain.

In the drawings :F igure 1 is a side view ofthe improved machine with parts in section, and Fig. 2 is a front view.

.In the present embodiment of the invention a frame is provided, comprising uprights 1 connected at their tops by cross bars 2 and 3, and at their bottoms by cross bars l and 5, the cross bars 2 and 4.- being at the ends of the frame, and the cross bars 3 and 5 at the sides of the frame. The cross bars are arranged between the uprights and at cross bars 2, 3, 4i and 5 the uprights are con nected by brace rods 6, the brace rods being alongside the respective cross bars. A shaft 7 is journaled in bearings 8 at one end of the frame, and a pulley 9 is secured to the end of provided at the said end with the shaft outside of the frame by means of a key 10, and. a bevel gear 11 is secured" to the shaft by means of a set screw 12 intermediate the ends of the shaft. A cylindrical casing 13 is supported longitudinally of the frame, the casing having one end closed, and being laterally spaced bearing arms 14 which are journaled per end of the casing is also closed, and an outlet opening 15 is provided at the said upper end, the outlet being lateral, as shown in Fig. 1. At its lower end the casing is provided with an inlet, and a. species of hood 16 is arranged at the inlet, the hood extending upwardly, as shown.

A feed hopper 17 is supported by the upper cross bars 2 and 3, and the hopper is provided with a feed opening at the hood 16, and delivering to the casing. The feed opening is normally closed by a door 18, mounted to slide on the bottom of the hopper, and an operating bar 19 is connected at one end of the door, the other end extending above the frame, for convenience in grasping to open or close the door.

An eye 20 is riveted to the casing near the opposite end from the shaft 7, and a flexible member 21, a chain in the present instanoe,-

has oneend connected with theeye. A hook 22 is secured to the upper Cross bar 2 at the end ,of the casing adjacent to the outlet opening 15, the hook being adapted to be engaged by a link of the chain, .to hold the hopper in inclined position.

Patented Nov, in, 1914.

Al'cro-ssibar 23 is arranged between the uprights at .the end of the frame adjacent to the shaft 7, and one of the arms 24 of an lb w is .held in a sectional bearing 25 ,onthebar.

The other arm 26 of the el ow e3;- tends downwardly along the front face of the hopper 17, delivering atthe outlet or feed opening of the hopper. A valve casing 27 is connected with the end 24: of the elbow, and the valve 28 in the casing controls the flow of-the solution through the elbow.

The outer end of the valve casing is designed to be connected to a container, as for instance a tank or a barrel containing the solution for treating grain, and as the grain is Jfed from the feed opening it is treated with the solution. It will be noticed that wlicn the door 18 is open, the feed opening for the grain is at the discharge of the solution, and the grain must fall directly through the spray issuing from the discharge nozzle.

A shaft 29 is journaled longitudinally of the casing 13, in bearingsBQ in the ends of the casing, and at the end'adjaeent to the gear wheel 11 the shaft is provided with a bevel gear 31, which meshes with the gear 11 before mentioned. A vane 32 is secured to the shaft spirally thereof, and the shaft and the vane constitute a conveyer, for con veying the grain from the. hood 16 to the outlet 15 of the casing.

The operation of the device is as follows: The grain to be treated is arranged in the hopper 17 and a suitable source of sup 1y for the solution is connected with the valve casing 27. A suitable source of power is connected with the pulley 9, for rotating the shaft 29, and when the machine is running the feed door 18 is opened slightly by means of the bar 19,-the valve 28 being opened at the same time. As the grain passes from the feed opening into the hood, it passes through the solution delivered by the elbow orx - ournaled transversely of t and every art of the grain is brought into contact wit the solution. B means of the chain 21 the inclination of t e casing may be varied, and a suitable receptacle is pro- .yided at the outlet 15 of the casing. The treated grain "passes into the hood and into the casing, and is moved toward the outlet 15 by the vane 32. As the grain moves u ward, the solution drains away from t e grain, passin down into the lower end of the casing. fter a certain amount of solution has entered the casing, just enough is permitted to enter by way of the elbow to supplythe loss carried away by the grain. By varying the inclination of the casing the grain may be drained more or less quickly, so that the grain can be delivered at the outlet practically dried.

We claim I A device of the character specified, comprising a supporting frame a driving shaft he frame at one end and near the bottom thereof, a tubular casing having its ends closed and provided at its lower end with longitudinally extendgrain, and having an opening at its upper side and lower end for receiving the grain, a hopper delivering to the last-named opening, a gate or valve for controlling the feed from the hopper, and a nozzle for delivering a liquid on the grain as it passes from the hopper.
